Elsewhere, Credit Suisse raised the stock's price target from $20 to $32, and Canaccord Adams increased its 12-month estimate from $21 to $29.

In fact, Wedbush Morgan is the lone bearish holdout this morning, with the brokerage firm bucking the trend by downgrading SPWRA from "outperform" to "neutral."

Professor Udall,

Do you have any opinions on Zoltek Companies, Inc. (NASDAQ: ZOLT)? My wife wants me to buy everything "green". Her last "green" company idea was General Electric (NYSE: GE). I know, right? I bought a little just to quiet the noise level. I'm into a little SunPower (NASDAQ: SPWR) and Evergreen Solar (NASDAQ: ESLR). Does Zoltek have legs?

Thanks,

Minyan L.

First, that's hysterical. Second, a word of caution: Going all green, or all of any one thing, is something I'd never advocate. If you do, you do so at your own risk, as nothing in the market is ever as obvious as it seems, especially when it seems totally obvious.

On Jim Cramer's STOP TRADING segment on CNBC at 2:45 PM EST, Cramer was discussing how to play oil prices dropping and a crock of something.

Now that oil has gone to $60, Cramer said he is tired of torture House game because that homebuilder group was the best performer over last month.

Cramer says Sell alternative energy stocks, particularly Ethanol plays. He says even sell solar power. He is discussing the stocks, not the technology. They showed SunPower Corporation (NASDAQ:SPWR), FuelCell Energy, Inc. (NASDAQ:FCEL), Aventine Renewable Energy Holdings, Inc. (NYSE:AVR), Verasun Energy Corporation (NYSE:VSE), Ballard Power Systems, Inc. (NASDAQ:BLDP). He said he is talking about the stocks, not the company.

Crocs, Inc. (NASDAQ:CROX) is up 6% and Cramer thinks they will preannounce upside to the quarter tomorrow at an investor conference presentation. He likes the closed toe cold weather and Disney deals. He says they are hot and go higher. He also noted for the short sellers to watch out.
